Each block is sired angle. Therefore the said plate has a universal connection with said clamp. As here shown, thek clamp is provided with a ball4 member 35, engaged in depressions formedin jaws 36, attached to said plate and clamped a means for holding asbestos or charcoal in any desired position relatively to the plate, This means comprises ytoothed plates 4l, having slotted shank portions42 43, extended outward, and clamping bolts 44 45 pass through the slots in said members 42 43 and also through slots 46 47 near the opposite edges of the plate. By this means the plates 40 and 4l may be turned at any desired angle or moved to any desired position on the plate and also moved toward or from each other. This plate 34 will be found useful for holding charcoal, against which the work held by the tweezers may be placed while soldering.

The operation of the device is quite evident from the above description. It is obvious that the tweezers 19 and 28 maybe turned to any desired angle toward each other as the work may require.

AHaving thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A work-holder, comprising standards, a screw-rod connection between the upper ends of the standards, a carrier-block movable on said rod, a nut engaging with the rod and with the block for moving the block along the rod, an arm attached to the block, and tweezers having universal-joint connection with ysaid arm, substantially as specied.

means for causing movements of said block, an arm extended upward and then downward from said block, a ball-joint member adjustable vertically on said arm, and tweezers having jaw members provided with depressions for receiving said ball'member, substantially as specified.

A work-holder, comprising standards, two rods connecting the upper portions of said standards, one of said rods being screwthreaded, blocks movable along said rods, nuts on the screw-rod and engaging with said blocks, arms carried by the blocks, and tweezers having universal-joint connection with said arms, substantially as specified.

4. A work holder, comprising standards having reduced screw-threaded upper portions, parallel rods removably placed on said reduced portions, one of said rods being screwthreaded, jam-nuts for holding the screw-rod as adjusted on said reduced portions, carrierblocks engaging with and movable along said rods, means engaging with the screw-rod for causing the movements of said blocks, arms carried by the block-s, and tweezers having universal-joint connection with said arms, substantially as specified.

5. A work-holder, comprising standards, a rod connection between the upper ends of said standards, work-holding devices adjustable along said rod, a plate adjustable on one of the standards, and clamping-plates adjustable on said first-named plate, substantially as specified.

ln testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
